Our Mission
Welcome to our tuition service based in the Mayfair Business Centre, Portadown—where expert teaching meets personal support. We specialise in Year 10 Mathematics, GCSE Maths and Science, and A-Level Biology and Chemistry, all delivered in-person in very small groups to ensure focused, high-quality learning. Our tutors are experienced professionals currently working in education, and each subject is taught by a dedicated specialist. Driven by a passion for education and a commitment to giving back to our community, we offer more than just academic support—we also provide a trusted network for parents, helping them navigate the complexities of GCSE and A-Level pathways and make informed decisions for their child’s future. Whether you're seeking academic excellence, tailored guidance, or a nurturing learning environment, we’re here to help every step of the way.
About Me
My name is Joseph Dennison, and I’m a passionate science educator with over 15 years of teaching experience. I hold a BSc in Anatomy and a PGCE in Science from Queen’s University Belfast. I currently serve as Head of Science and a member of the Senior Management Team at one of Northern Ireland’s largest secondary schools. I specialise in teaching GCSE Science and A-Level Biology, and I’m deeply committed to helping students reach their full potential. My approach is rooted in active, engaging lessons that draw on evidence-based pedagogies and research-driven learning techniques. I founded Stellar Tuition to extend this high-quality, personalised support beyond the classroom and give back to the local community by helping students—and their families—navigate the path to academic success.
